Septic Tank Installation Saskatoon SK
Installing a septic system is one of the most important infrastructure decisions you will make for a rural or acreage property. Saskatoon Excavating guides property owners through every stage of the septic tank installation process — from permits and soil testing to excavation, installation, and final inspection. We ensure your system is properly designed, correctly installed, and built to perform for decades.
How much does a Septic Tank Installation Cost?
The cost of a new septic tank installation in Saskatchewan typically ranges from $5,000 to $20,000. Several factors affect the final price including tank material, system type, property size, soil conditions, and site accessibility. Saskatoon Excavating provides a detailed estimate after assessing your property so you know exactly what to expect before any work begins.

Septic Tank Installation Process
Installing a septic system in Saskatchewan requires careful planning, licensed design, and proper permitting before excavation begins. Here is what the process involves from start to finish.
Percolation Test
A percolation test, commonly known as a perc test, is legally required before any septic system installation in Saskatchewan. It analyzes soil composition and drainage capacity at the proposed installation site to confirm the land can support a septic system. The results determine what type of system is appropriate and where it can be located on the property.
Land Survey
A land survey establishes the exact boundaries of your property before installation begins. This step is critical to ensure the septic system is installed within your property lines and does not encroach on neighboring land or municipal easements. Skipping this step can result in costly legal disputes and system relocation.
Excavation and Installation
Once permits are approved and the design is finalized, excavation begins. A minimum of one inch of washed stone is placed beneath the system to support drainage. A licensed septic system designer oversees the installation to ensure compliance with Saskatchewan health regulations. All components including the tank, pipes, and drain field are installed to specification.
Testing and Backfilling
Before backfilling, the system undergoes a full series of tests including water testing, pressure testing, vacuum testing, and leak testing. Only after all tests are passed does backfilling proceed. This ensures the system is structurally sound and fully sealed before it is put into service.
Type Of Septic Tanks
Septic tanks are manufactured from four primary materials — concrete, plastic, fiberglass, and steel. Each has distinct performance characteristics relevant to Saskatchewan conditions.
Concrete Septic Tanks
Concrete tanks are the most common choice in Saskatchewan due to their durability and longevity. A properly installed concrete tank can last 40 years or more. However, concrete is susceptible to cracking from soil movement and freeze-thaw cycles, which is why proper installation depth and backfill compaction are critical.
Steel Tanks
Steel tanks are rarely installed today due to their susceptibility to rust and structural deterioration over time. If your property has a steel tank, it is likely aging and should be assessed for replacement.
Plastic and Fiberglass Tanks
Polyethylene and fiberglass tanks are lightweight and cost less than concrete. They resist corrosion and are easier to transport to remote sites. However, they are more vulnerable to damage during installation, particularly in high water table conditions where buoyancy can be a factor. Local regulations require a plastic distribution box when these tanks are used.
Types of Septic Systems
Conventional Septic System
The conventional septic system is the most widely used system in Saskatchewan. It uses a watertight tank to treat sewage before it disperses into the drain field. There are two variants:
Gravity-Flow: Wastewater flows from the home by gravity into the tank, then through perforated pipes buried in gravel in the leach field, where it is treated by soil bacteria.
Pumped: Wastewater flows by gravity into the tank, then a pump moves it to the absorption field. The pump is typically housed in a concrete pit.
Alternative Septic System
Alternative systems are used when soil conditions, water table depth, or lot size make a conventional system impractical. Pressure distribution systems use pumps to move wastewater to the leach field at a controlled rate, allowing more time for treatment. These systems require annual maintenance by a licensed operator and must follow the manufacturer’s operation and maintenance manual.
Anaerobic Septic System
Anaerobic systems treat wastewater without oxygen, making them suitable for areas without a significant water table. They are more commonly used in commercial and industrial applications than in residential settings.
What are the benefits of having a septic tank
A properly installed septic system offers several long-term advantages for rural and acreage property owners. It operates independently from municipal sewer infrastructure, contains its own filtration system, and is more environmentally contained than public systems — a failure affects only the immediate property rather than the broader community. High-quality systems installed correctly can last 30 to 40 years with proper maintenance, making them a sound long-term investment.
FAQ About Septic Tank Installation in Saskatoon
Can I install my own septic tank?
Septic tank installation in Saskatchewan requires licensed designers, certified contractors, and approved permits. DIY installation is not recommended and in most cases not legally permitted. Errors made during installation are costly to correct and can result in system failure, contamination, and significant fines. Saskatoon Excavating handles the entire process to ensure your system meets all regulatory requirements.
How long will my septic tank last?
A properly installed and maintained septic tank typically lasts 20 to 30 years. High-quality concrete tanks can exceed 40 years with regular pumping and inspection every 1 to 3 years. Steel tanks deteriorate significantly faster and should be assessed for replacement if your system is more than 15 to 20 years old.
Should I repair or replace my septic tank?
The decision depends on the age of the system, the type and extent of damage, and the cost comparison between repair and replacement. Minor issues such as baffle failure or pipe damage are generally worth repairing. If your tank has collapsed, your drain field has fully failed, or you have experienced repeated system failures, replacement is usually the more cost-effective long-term decision.
